Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

In valid screening studies for ready biodegradability, no significant biodegradation was found, either with the entire UVCB substance Oligomerisation and alkylation reaction products of 2-phenylpropene and phenol [EC no. 700-960-7] or with two main constituents, the phenolic constituent p-cumylphenol [CAS no. 599-64-4] and the dimeric non-phenolic constituent, 4-methyl-2,4-diphenylpent-1-ene [CAS no. 6362-80-7] (*). However, the latter proved to be biodegradable in a study acc. to OECD 302 C [MITI(II) test] (see following endpoint summary "Biodegradation in water (2)" along with the robust study summary).


(*) = 1,1'-(1,1-dimethyl-3-methylene-1,3-propanediyl)bisbenzene (EC no. 228-846-8; CAS no. 6362-80-7)
